[April 25, 2014]SEOUL (Reuters) — U.S. President
Barack Obama said on Friday that reclusive North Korea posed a threat
not just to the region but to the United States and that he hoped China
would use its influence to rein in its ally.

In March, the North warned it would not rule out a "new form"
of nuclear test to boost its nuclear deterrent, after the U.N.
Security Council condemned Pyongyang's launch of a mid-range
ballistic missile into the sea east of the peninsula.

North Korea has been under U.N. sanctions since its first
nuclear test in 2006, banning it from conducting atomic and
missile tests, barring U.N. member states from weapons trade
with Pyongyang and financial transactions that facilitate them.

It regularly threatens the United States and South Korea with
destruction.
